Sand is delivered into one side of the "pyojector by an inciinod chute the iowor and of which is supportod on the piojactor-casing 2'1 and the upper end on th ca..iiago-standa'rd 13.

bearing socket il is rigidly secured and clan'iped to the jib 39 by a ei-bolt l2. it spindle 43 is rotatably mounted in socket i1. A tubularnrm -14 has its inner end secured to spindle 43 by a U-bolt which passes around the spindle and through said arm. A plate l6, zUlZIPtQCl to serve as a support for a flask to be filled with sand from the pro-- jector, is mounted on a stud 427 which is rotatably held in a socket at? which is secured by a U-bolt -18 to the outer end of arm 44. The axes of the pivotal connections for the jib and arm and plate are vertical so that the plate 46 will remain horizontal and the angle of delivery of the sand from the proj e'ctor' into the flask will not be varied, While the pivotal connectionsfor the jib and arm permitthe flask and support 'efi to be moved horizontally in any direction so that all portions of the flask may be brought into position to be filled with sand from the projector. This construction exemplifies a ma chine in which the projector is. mounted upon movable carriage and the latter is provided with a .movable flask supportwhich is mounted on the carriage and movable relatively thereto.

The carriage is rotatable so that it may be moved in circular path over an area of the floor on which the molding sand has been shoveled and to progressively advance over this' area as the sand on the floor is fed to the machihe. l-Vhile the machine is rotatahly advancing, sand may be placed in back of it so'that the machine will be continuously supplied with sand. A screw-conveyer 50 is'securcd to a shaft 51 which has its outer end mounted in an extension 52 of the back 14 and its inner end in a bearing Fig. 2 is a rear elevation. Fig. I, is a detail the back 14 is curved, as at to cooperate with the screw in feeding thev sand. to an elevator adjacent the inner end a of the screw-conveyer. This elevator consists'ot an endless chain 55 and buckets-56. These. buckets are' mounted on the spindles 57 which connectthe linkstof thechain and project from oneside thereof. The buckets are mounted on the projecting portions of said spindles and disposed at one side of the chain instead of in alincnient therewith. Ry this arrangcn'ient, the con\ 'e wrr-chain is kept free from sand. (Thain 55 passes around a. sprocket 58 fixed to the screw-conveyer shaft 51, a sprocket 59 which is mounted ad jacent one end of 'a lever 60 and a sprocket- (Sladjacent the other end of said lever. The latter is pivoted between the sprockets, as at 62, and is'lield in position to keeptlie chain. under the desired tension b a. cable '63 which is connected to one end of the lever 60 and has its other end connected to an adjustable drum t i. A spring is included in the cable gages and is driven by a sprocket 66. Be sides operating the elevator buckets, this ihain operates the sprocket 58 on the screw-' conveyer shaft. Sprocket 66 is secnreo to a shaft 6? which is mounted in a bearing '8 formed of sections. and bolted to the floor-- of-the molding room andwith which gear 72 meshes, and reducing gearing driven from the, screw-conveyor shaft 51 to cause the carriage to rotateslowly so that the screw will be kept suppliedwith sand. This gearing comprises an eccentric or wrist-pin 74. on the otter end of'shaft 51, a. pawl 75 pivoted on the wrist pin and pressed by a spring 76 into en 'agement with a ratchet- Wheel 77'Wl1i6l1 is ournaled onthe stud 73, a pinion 78 on the hub of ratchet 77, idler inions 79 journalednn the studs 80 on the bracket 52 and internal gear-teeth 81 on the gear-Wheel 72. As tliesha ft 51 is ro- Chain 55 also em tea titted, the wrist-pin 7% Will operate pawl 75 to rotate the i'a tchetwvheel 77 step-bystep. The gearing between ratchet 77 and gear 72 will cause the Wheel 77 to be driven at a reduced speed. Rotation of gear 72, which meshes with the stationary rack, will cause the carriage on which'the'projector, elevator and teed-mcchanism are mounted to be rotated. A dog- 83 pivoted to the bracket 52, is provided with a. terminal 84- which is adapted to ride in the rack 71 and is yieldingly held in engagement therewith by a spring: 85. This'dog serves to remove the sand from and clear the rack 7i in advance of the. gear 72.

The operation of the machine will be as follows: the flask :32 to.be filled and with the pattern therein is placed on-the support or table 46 will force the sand toward the inner end thereof and solthat it will be picked up by tl'ieuelevator buckets 56 which will 'ele ate the sand and dump it onto the screen 83 through which the sand will fall into the chute 32nnd be delivered into one side of the projector lhe projector blade 3i will be o 'ierated to propel the packed wads of sand at a peed ranging from approximately int 25 sand to the projector.
